JOHN SINNAMON, OF OSWEGO, NEW YORK.

MACHINE FOR STRETCHING AND DRYING CLOTH.

SPECIFICATION forming part of Letters Patent No. 232,854, dated October 5, 1880. Application filed July 19, 1880. (No model.)

To all whom t may concern.-

Be it known that I, J oHN SINNAMON, ot'Oswego, in the county ot' Oswego, in the State of New York, have invented new and useful Iniprovements in Machines for Stretching1 and Drying Oloth, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the tentering-chains employed for conveying cloth coated with sizing through a prolonged drying-frame and stretching said cloth during the process of drying, and has more particularly reference to that class of tentering-chains which are guided by stationary pulleys or friction-rollers.

The invention consists in an improved construction of said tentering-chain and means for guiding the same in its movement through the cloth drying and stretching apparatus, whereby increased strength is imparted to the said chain and a more accurate movement with less friction of same is obtained.

The invention is fully illustrated in the accompanying drawings, wherein Figure l is a transverse section of my improved tenteringchain, with an end view of the means for guiding the same. Fig. 2 is a plan view of the aforesaid devices for guiding the chain. Figs. 3 and 4 are side and plan views, respectively, of sections of my improved tentering-ch ain, and Fig. 5 is a side view ot' said chain and the means for guiding it.

Similar letters of reference indicate corresponding parts.

A represents a bracket or hanger bolted to the top of the string-timber B, which is extended the length of the cloth stretching and drying' apparatus in the usual manner.

The hanger A is formed with a goose-neck, a, which overhangs the inner edge of the stringer B, and is provided at its extremity with a vertically-socketed head, b.

In the socket of the head b, from the under side thereof, is secured'a pin, c, having on its lower end a head, between which and the under side of the head b is a pulley or roller, d, pivoted to said pin, said roller having at its upper end a horizontally-projectingperipheral itlange, c.

In a socket, f, on the base ot' the bracket A is secured horizontally a pin, g, the axis of which is at right angles to and in a perpendicular line from the axis of the roller d.

Upon the pin g is mounted a roller, h, which is provided at its outer end with a peripheral flange, t', and at its rear end with a circun1- feren tial groove, 7c, the forward face or shoulder ot which is in a perpendicular line with the rear face of the upper roller, d, as shown in Fig. 1 ofthe drawings.

l lrepresent two links of a chain, which links are formed ot' flat bars of metal of equal lengths and heights, and secured parallel to each other by bolts m passing through the ends of said links and shouldered against the inner sides thereof. The said links are formed at one end with an inward offset, so as to receive on their outsidethestraightendof thesucceedinglinks and main tain the exterior surface of the chain straight. The successive links of the chain are coupled by the bolt m passing through their extremities. The links lare of proper height to allow them to pass horizontally between the under side of the roller d and top of the roller h without undue vertical play, and the bolts m are of such lengths from shoulder to shoulder as to bring one link close to the Hanger' and the other link close to the edge adjacent to the groove 7c of the roller h.

To the outside of the link, abutting against the liange z', is attached an L-shaped plate, u,

usually made of brass, and having secured to its horizontal flange the tenter-hooks 0, upon which is hooked the edge of the cloth undergoing the drying' and stretching process.

To the outer side of the link, near the groove 7c, is firmly attached a Wider link, p, which travels in the groove k of the roller h, and bears with its upper end against the rear face of the pulley d and the upper llange, e, thereof. The strain incident to the stretching of the cloth attached to the tenter-hooks o is transmitted to the wide link p by the links Z l and their connecting-bolts m, and this strain is resisted chieily by the before-described bearings of the wide link in the groove of the rollers l1, and on the rear face of the roller d, and thus to a great extent the strain on the outer end of the roller 7L and the friction on the flange thereof are reduced. The rear link, l, being rigidly secured to the link p, serves to thoroughly brace the same, so as to prevent its yielding to the lateral strain.

It will be observed that by this peculiar construction and combination of the chain and its carrying-rollers the Weight of the chain and cloth attached thereto moves over horizontally-pivoted rollers, which at the same time aid in resisting the lateral strain.

Furthermore, by my improvements each set of carrying and guide rollers h and Z are pivoted to one hanger, A, and are thus secure in their relative position. Said hangers being all made after one pattern and the rollers h and d being tted alike to all of them greatly facilitates their alignment in the stretching and drying machine.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In combination with the tentering-chain composed of the links l Z, of equal height, and the wider link p, attached to the outer link, l, and the vertically-pivoted roller d, provided with iiange e, the horizontally-pivoted roller h, arranged diametrically beneath the roller d andprovided with the flange fi at its outer end, and with the groove 7c in a perpendicular line with the rear face of the roller d, substantially as described and shown.

2. The combination of the bracket A, provided at its base with the socket f, and having the goose-neck a, with a socketed head, b, the pin c, extended vertically through the head b, the flanged roller d, pivoted on pin 0, the roller h, provided with ange z' and groove 7c, the horizontal pivotal pin g, secured in socket f, and the chain composed of the links L Z, of

equal height, and wider link lo, attached to the outer link, l, substantially in the manner described and shown.

In testimony whereof l have signed my name and affixed my seal in the presence of two attesting Witnesses, at Syracuse, in the county of Unondaga and State of New York, this 6th day of July, 1880.

JOHN SINNAMON.
